Quality Control

Our Poly(Propylene Oxide), Diurea Terminated is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Certificates of Analysis (COA) detailing key parameters such as hydroxyl value, urea content, and molecular weight distribution are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive). To prevent moisture uptake and maintain product integrity, containers must be kept tightly sealed when not in use. Recommended storage temperature is 15-25°C.
